Bonus depreciation does something Section 179 cannot: it creates a loss. An oilfield service company that buys several units in a year and takes bonus depreciation on the purchase price can drive taxable income into negative territory, generating a net operating loss that carries forward to offset future years' income. For operators deploying significant capital into rigs, frac pumps, or compressor packages in a strong year, the ability to create and carry an NOL is a meaningful planning tool.
The percentage of the purchase price you can deduct in year one under bonus depreciation has changed over time as Congress has adjusted the provision. For current figures, your CPA is the right source; do not rely on a web page for the active percentage. What does not change is the core mechanics: equipment placed in service during the tax year qualifies, the deduction is taken in addition to (or instead of, depending on the structure) regular depreciation, and the deduction can exceed your taxable income.
Financing the equipment purchase does not change the tax treatment. You place the equipment in service, you own it (or are treated as owning it under a qualifying lease structure), and your CPA claims the depreciation on the return. The loan or lease sits on the balance sheet; the deduction sits on the income statement. The lender is not involved in the depreciation calculation.
What financing does is allow you to preserve cash while capturing the deduction. An operator who buys a frac spread for $3,000,000 and finances 80% of it puts $600,000 down and retains the rest in operating capital. The bonus depreciation deduction, however, applies to the full purchase price, not just the down payment. The tax benefit is calculated on the $3,000,000, while the cash out of pocket was $600,000. That leverage is the reason equipment financing and depreciation planning often go together for oilfield service companies making large capital investments.
For hydraulic fracturing companies adding Tier 4 pump units or a complete frac spread, the combined financing and depreciation strategy can substantially reduce the after-tax cost of new equipment. The upfront cash requirement is limited to the down payment, the monthly payment is manageable against the day rates the equipment generates, and the depreciation reduces the tax liability on those day rates.
Congress extended bonus depreciation to used equipment that is new to the taxpayer, which changed the planning calculus for oilfield operators buying second-hand iron. A used equipment purchase of a workover rig from another operator, or a late-model vacuum truck from an estate sale, can now qualify for the same first-year deduction as new iron straight from the manufacturer.
This matters in the oilfield because used equipment dominates the transaction volume. Very few oilfield service companies buy only new iron. The used market, especially during upturn cycles when operators are fielding stacked equipment, produces most of the transaction flow. Knowing that a used wireline unit purchased at auction in the Permian carries the same tax treatment as a new one ordered from the manufacturer opens the depreciation conversation to the full range of equipment a service company might buy.
The used-equipment rule comes with one condition: the equipment cannot have been previously used by the same taxpayer or a related party. An operator who sold a rig two years ago and buys it back does not qualify for bonus depreciation on the re-purchase. New-to-you from an independent third party is the standard, and in the oilfield service market, that covers the vast majority of used transactions.
Bonus depreciation is available on equipment loans where the borrower holds title, and on dollar-buyout leases where ownership is the clear intent of the transaction. FMV leases typically do not qualify because the lessee does not own the asset during the lease term. If year-one depreciation is central to the planning, confirm the lease structure with your CPA before closing.
For transactions where the operator is combining Section 179 and bonus depreciation, the order of application matters and affects how much of each provision gets used. Section 179 is typically applied first, up to taxable income, and then bonus depreciation absorbs the remaining eligible basis. The CPA manages this calculation, but the financing structure needs to be in place before year-end for any of it to work.
Timing is always the critical variable. Equipment that is ordered, delivered, and placed in service before December 31 qualifies. Equipment that ships on December 30 but is not operational until January does not. For large pieces of equipment with delivery lead times, particularly mud pumps or compressor packages that require installation and commissioning, the ordering timeline has to account for the entire process, not just the delivery date. We can sometimes accelerate the financing close to help meet a year-end placed-in-service date, but we cannot compress a six-week installation timeline.
Oilfield service company income is lumpy. A service company might earn significant taxable income in a strong commodity cycle and very little in a soft year. Tax planning that uses depreciation deductions in a high-income year and carries the NOL forward into uncertain years reduces the tax cost of the cycle, not just the individual year. Operators who buy equipment near cycle peaks, when they have income to shelter and the equipment to deploy, get more value from the depreciation than operators who buy on the downswing when there is less income to offset.
For gas compression companies adding packages to expanding gathering systems, and for workover and well service operators picking up additional rigs during a rig count upturn, the combination of accelerated depreciation and equipment financing is standard practice. The equipment goes into the field, generates day rates, and the depreciation shelters a portion of those rates from current taxation. It is not a loophole; it is what the provision is designed to do for capital-intensive businesses.
Straight answers about bonus depreciation financing, documentation, timing, and equipment eligibility.
Yes. The outstanding loan balance has no effect on your ability to claim depreciation. Depreciation is based on ownership and use in business, not on whether the asset is paid off. You can be in year one of a five-year loan and still claim bonus depreciation on the full purchase price in year one of ownership.
Both allow accelerated deductions, but they work differently. Section 179 is limited to your taxable income and cannot create a loss. Bonus depreciation has no income cap and can generate a net operating loss that carries forward. Section 179 has an annual deduction limit that phases out at high purchase volumes; bonus depreciation does not. For large equipment purchases in a profitable year, your CPA will typically apply Section 179 first and then use bonus depreciation for the remaining basis.
Yes, assuming the bonus depreciation percentage is 100% (verify the current rate with your CPA). The deduction is based on the purchase price, not the down payment or the financed amount. A 100%-financed purchase with no cash out of pocket still generates the full depreciation deduction in year one. That is one of the reasons equipment financing and depreciation planning work so well together.
Yes, provided it has not previously been used by you or a related party, and assuming it qualifies as tangible personal property used in your business. The IRS extended bonus depreciation to used equipment to allow second-hand transactions to receive the same treatment as new purchases. Document the purchase clearly and retain the bill of sale and title transfer records.
That is the design of bonus depreciation. The excess deduction creates a net operating loss, which carries forward to future tax years and can offset future income. Oilfield service companies often use this deliberately: take a large depreciation deduction in a moderate-income year, create an NOL, and carry it forward into a high-income year when the tax benefit is worth more.
